AD9200完整的10位20MSPS，80毫瓦cmos模数转换器

　　The AD9200 is a monolithic， single supply， 10-bit， 20 MSPS analog-to-digital converter with an on-chip sample-and-hold amplifier and voltage reference. The AD9200 uses a multistage differential pipeline architecture at 20 MSPS data rates and guarantees no missing codes over the full operating temperature range. The input of the AD9200 has been designed to ease the development of both imaging and communications systems. The user can select a variety of input ranges and offsets and can drive the input either single-ended or differentially. The sample-and-hold （SHA） amplifier is equally suited for both multiplexed systems that switch full-scale voltage levels in successive channels and sampling single-channel inputs at frequencies up to and beyond the Nyquist rate. AC coupled input signals can be shifted to a predetermined level， with an onboard clamp circuit （AD9200ARS， AD9200KST）。 The dynamic performance is excellent. The AD9200 has an onboard programmable reference. An external reference can also be chosen to suit the dc accuracy and temperature drift requirements of the application
